Moffatt's 1976 debut, Katy, is considered a classic of progressive country, demonstrating the Fort Worth, Texas native's ability to draw together folk, rock, country and blues material into a coherent whole. Throughout her interpretations, she maintains the integrity of country music while providing listeners with passionate vocal interpretations. There is a somber quality to her slower paced songs, serving to highlight her delicate voice. In contrast, her faster paced songs project an edgier sound. Most of her music emulates western characteristics, but, occasionally, you can hear bluesy undertones.
In addition to producing original music, Moffatt also does some cover work, both of which can be found on her latest album, Fewer Things. Collaborator, Andrew Hardin, is featured on this album as well, adding his acoustic guitar chops to the mix.
